Fretz Canal

What Fretz Canal does

Fretz Kanal-Service AG is a privately held Swiss canal infrastructure services company headquartered in Cham, Canton Zug. Founded in 1954, the firm operates as the Fretz Unternehmensgruppe from six locations — Cham, Baar, Küssnacht a.R., Altdorf, Einsiedeln, and Sursee — covering the cantons of Zug, Schwyz, Uri, and Luzern, with project reach into Zürich, Basel-Stadt, and Aargau. It serves a horizontally diversified customer base spanning private homeowners, commercial enterprises (retail, restaurants, industrial facilities, shopping centers), and public institutions (municipal and cantonal governments), with services delivered on a 24/7 basis via two emergency hotlines and dispatched from regional offices.

The company operates four core service lines: Kanalunterhalt (canal cleaning, drain/pipe unblocking, suction work and shaft recycling with high-pressure water jet vehicles up to 2000 mm diameter); Kanalsanierung (trenchless rehabilitation using GRP and felt hose liners cured by UV or peroxide, KA-TE PMO+Pipetronics robotic renovation, Quik-Lock point repairs, and shaft rehabilitation); Kanalinspektion (CCTV inspection with georeferenced tracing, laser deformation/diameter measurement, and calibrated digital leak tightness testing); and Strassen- und Flächenreinigung (specialized wet/dry street and surface cleaning). The fleet integrates internal water recycling systems that allow canal cleaning without potable water consumption, supporting ISO 14001 environmental certification. Inspection and renovation work is certified across multiple vendor systems (iMPREG GL16, PL Flex 3D).

Fretz generates revenue primarily through professional-services contracts billed per project or per job, with quote-based pricing that is not publicly disclosed; reference municipal and enterprise contract sums span CHF 10,080 to CHF 425,595. The go-to-market is sales-led and regionally anchored, leveraging the physical office network, phone-based emergency intake, an online Offertanfrage form, and recurring maintenance contracts with commercial and municipal clients. Since 2012, ownership has rested with four entrepreneur families (Emilio Baldini, Thomas Iten, parts of the Risi family, and Reto Hürlimann, the CEO), who have executed a disciplined buy-and-build program adding five acquisitions between 2021 and 2025 and growing group headcount from approximately 85 to 120.
